THE CANADIAN ENTOMOLOGIST. 91 



profuse irregular fuscous mottlings irregularly distributed, the anal line of 

 the lighter colour, but sometimes obscure, the intercalary vein arcuate 

 only at extreme apex, subequidistant throughout (and not very distant) 

 from the median vein, the lower intercalary area broad and rather densely 

 filled with anastomosing nervules, but not more densely than the area 

 beneath it, the axillary vein united apically with the anal. Wings bright 

 red (or occasionally citron?) at base, vitreous at apex, with heavily 

 infuscated veins, and an extramesial, strongly arcuate, transverse fuscous 

 band, about half as broad as the tegmina, tapering a little along the 

 hinder margin, failing to reach the anal angle and leaving three marginal 

 lobes free at the apex ; it sends a stout humeral vitta to the very base. 

 Hind femora cinereous, twice banded very obliquely and not very 

 broadly with fuscous, very broad, the inferior carina rather high and 

 rather strongly arcuate, the inferior sulcus red ; hind tibite red, paling 

 basally, or luteous. 



Length of body, 36 mm.; antennas, 9 mm.; tegmina, 29 mm.; hind 

 femora, 16 mm.

This species is closely related to H. calthulus (Sauss.),but differs from 

 it in the sharper median carina and lateral canthi of the pronotum, the 

 disc of which is less coarsely rugose ; the transverse fuscous band of the 

 hind wings is also narrower. 



Hippiscus croceus, sp. nov. — Fusco-griseous, rather robust, and con- 

 siderably below the medium size. Head moderate, pale cinereous 

 excepting above, the summit gently tumid, transversely rugulose, feebly 

 carinulate throughout ; fastigium of vertex not deeply impressed, but with 

 distinct walls, hexagonal, open behind, as broad as long, the front portion 

 separated off by a low transverse ridge to form a divided frontal fastigium ; 

 frontal costa moderately broad, subequal, scarcely contracted either above 

 or below the ocellus, moderately sulcate at and below the ocellus, 

 punctate above ; antennae a little shorter than head and pronotum, 

 apically blunt and scarcely attenuate on last two joints in the female, 

 testaceous, apically infuscated. Pronotum expanding moderately on the 

 metazona, the disc of which is faintly tumid with not very frequent short 

 longitudinal rugpe throughout, the process rectangulate with rounded 

 angle and subcrenulate margin, the prozona posteriorly impressed, 

 transversely plicate, the median carina slight, percurrent, the lateral 

 canthi distinct but not sharp, the posterior margin of the lateral lobes
